The Submarines are amazing. Gogol Bordello I started listening to, same with M83. So far I am pleased with all the bands I didn't know. The Submarines / Gogol are the main reason I am going, musically at least.
I wouldn't doubt it, yea Dan Auerbach is doing a solo show in seattle at the showbox, but I think he will come back with the band and play sasquatch this year. They opened for Stone Temple Pilots at last years Bumbershoot.
